Question

Identify the correct equation related to the mechanism of biological nitrogen fixation.

• A. N₂+8H⁺+8e^-+16ATP 2NH₃+H₂+16ADP+16Pi
• B. N₂+6H⁺+8e^-+12ATP 2NH₄⁺+12ADP+12pi
• C. N₂+8H⁺+6e^-+16ATP 2NH₃+H₂+16ADP+16pi
• D. N₂+6H⁺+6e^-+12ATP 2NH+12ADP+12pi

Answer 1

The correct option is A

N₂+8H⁺+8e^-+16ATP 2NH₃+H₂+16ADP+16Pi

In biological nitrogen fixation, one molecule of nitrogen requires $8H^{+},8e^{-}$, and 16 ATPs to produce two molecules of ammonia.
